Drainage fitting for a retaining wall



FIG. 1 is a perspective view of the drainage fitting showing my new design;

FIG. 2 is a right side view of the drainage fitting;

FIG. 3 is a left side view of the drainage fitting;

FIG. 4 is a top view of the drainage fitting;

FIG. 5 is a bottom view of the drainage fitting;

FIG. 6 is a rear view of the drainage fitting; and,

FIG. 7 is a front view of the drainage fitting.

The areas inside the broken boundary lines of FIGS. 6 and 7 form no part of the claimed design.
